Résumé
Acquired idiopathic generalized anhidrosis (AIGA) is a very rare disease, and its pathogenesis is poorly understood. We here report on a 20-year-old man presenting with a history of inability to sweat, small wheals, and occasional heat intolerance since 3 months. On provocation test, there was no sweating over the entire surface of the body, excluding the palms and axillae. His medical history was unremarkable and laboratory examination findings were all normal. There was no familial history suggestive of neuroendocrine disease. Based on these findings, we diagnosed acquired idiopathic generalized anhidrosis. To our knowledge, this is the first case of AIGA in Korean dermatologic literature. Herein, we report a rare case of AIGA.

Trichophyton tonsurans is an anthropophilic dermatophyte that is not yet truly prevalent in Korea. Especially, cases of toe nail infection during childhood are very rare, and no cases have been reported prior to this report. We report a single case of tinea unguium due to T. tonsurans in a healthy child. A 7 year-old patient visited an outpatient clinic presenting with subungual hyperkeratosis of the 1st and 3rd Rt. toe nails, which had first presented at an age of 28 months, and no other symptoms. Numerous hyphae were evident on the KOH smear examination. A confirmative diagnosis of tinea unguium cased by T. tonsurans was made after culturing scales from the toe nail lesion. The patient is currently undergoing follow-up, after being treated with oral terbinafine hydrochloride, without a relapse in symptoms.

Cutaneous larva migrans (CLM) is an uncommon cutaneous creeping eruption caused by the invasion and migration of nematode larvae into the skin. Burrowing larvae produce intensely pruritic, serpiginous, raised erythematous skin lesions. Most cases of CLM reported in Korea involved travelers returning from endemic areas with tropical or subtropical climates. We report herein a case of CLM with no history of travelling to endemic area and briefly review the relevant literature.

Cervical accessory tragus is a rare congenital malformation presenting at birth as a firm nodule on the neck along the anterior edge of the sternocleidomastoid muscle. It has also been reported under different names, such as elastic cartilage choristoma of the neck, Meckel's cartilaginous remnant, cervical tab, cervical auricle, and wattle. Histologically, cervical accessory tragus is composed of numerous hair follicles, and a prominent connective tissue framework in the subcutaneous fat and central core of cartilage. We report a case of an 8-year-old female who presented with a solitary flesh colored papule on the posterior neck that was histopathologically diagnosed as cervical accessory tragus.

Cutaneous pseudolymphoma refers to a heterogeneous group of benign reactive T- or B-cell lymphoproliferative diseases of the skin that resembles cutaneous lymphoma both clinically and histologically. Although most pseudolymphomas develop from unknown causes, various stimuli can induce pseudolymphomas. Pseudolymphomas have developed followed medications, infections, insect bites, ear piercing, and gold. To date, no case of pseudolymphoma developing after gold acupuncture has been reported in the Korean dermatologic literature. We report a case of a 49-year-old female who presented with multiple skin-colored papules on the left lower eyelid that showed features of a pseudolymphoma based on histopathologic assessment.

Dopamine is a catecholamine used in the treatment of circulatory shock of various etiologies. The usual dose range used is from 1 to 25 ug/kg/min. When used at higher doses, the prominent effect of dopamine on the vasculature is vasoconstriction induced by stimulation of alpha-adrenergic receptors. We report a case of dopamine gangrene. The gangrene developed on the injection site in the right dorsum of foot in a 43-year-old man during infusion of dopamine for treatment of septic shock. The gangrenous lesion healded after change of injection site to subclavian vein. The dosage of dopamine was not higher, we think that the gangrene developed due to the local vasoconstriction caused by dopamine leakage from the vessels.
